Greetings,
First, the process I'm using should be considered more of a dairy of how I did this not a how to. This 3" 3 Ring Binder are Notes and Photos of what I did including Mistakes. For me it's as important to know why/how it didn't work as that something work on first try. You have to be willing to start over until it works. If you see things that might help others in the future not to make mistakes feel free to comment. The Metal Bandsaw/Hacksaw is not a righteous Bandsaw and the Rollers only come down about 2 1/2"- 3" so in the photo that's just what I had to work with. Later I will be showing how I cut the Grooves in the bottom of the Pan with a Knife Edge Rotary File. Your Technique of using the Wheel to grind the grooves sounds like a Great Idea. You had not yet written about it before I did my Technique. I must say it sounds good. I used lapping compound to fit the Tapered Breech Block on the Girardoni I made. It was my opinion that to get an Air Tight Fit it should be Tapered and Tight. When Robert Beeman cam back with his original he took it to a machinist and found it was in fact Tapered. He asked me how I knew? I said when you make things you look at things differently. So I knew about gringing/fitting pieces together but just hadn't applied it. It's what happens when you work by yourself. I'll try to post more later today.

Greetings,
Thanks for thoughts. First I'd like to say that these are like diary 3" 3 Ring Binder notes to remember me of what I did for future projects. I put in them things that worked and ones that didn't. For me knowing what didn't work is just as important. And no I couldn't bring the Metal Bandsaw/Hacksaw rollers any closer, I know it's better but this is what I have. And your Technique of Grinding the 2 pieces together is sound. I had already figured out my technique of free hand cutting/grinding with a Knife Edge diamond rotary File before you had written yours. But I do like your Technique, I used a similar technique when I made the Girardonis to make the Breech Block tapered and Air Tight.
